Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disperse dye ink for ink jet, an ink jet printing method using the ink, and a printed material obtained by the method.

[0002]

2. Description of the Related Art Recently, application of an ink jet recording system developed for paper to textile printing has been studied, and practical application has been studied. Unlike conventional printing, ink jet dyeing requires jetting a dyeing liquid as droplets from a fine nozzle, so that ink ejection stability and reliability are important. In addition, in order to express a wide range of colors with a limited number of ink colors, the basic ink colors are required to be clear without color turbidity, to have high color value, and the like.

Further, in the case of ink-jet dyeing, unlike ordinary printing, fine droplets only adhere and absorb on the fabric, so that they are excellent in dyeing characteristics such as reproducibility of dyeing, fastness and stainability. And a clear image must be obtained without bleeding the ink on the fabric.

Further, when an ink using a disperse dye is produced on a cloth to be printed using a disperse dye, for example, a polyester cloth, and the ink is printed and dyed on the cloth, a plurality of inks having different color tones are printed on the cloth. In the case of color mixing by overprinting with, the density after dyeing, the color tone, the reproducibility when dyeing under the same dyeing conditions are very different depending on the combination of dyes used, and this method is still It turns out that there are cases where it is not enough.

[0005] In particular, if there is a difference in fastness due to a difference in dye, it is difficult to satisfy a well-balanced color developing property and a wide color reproducibility.

When expressing black with a disperse dye, it is common to use a plurality of dyes in combination. This is because, in many cases, a single dye was not sufficient as black and hue, and the density was often insufficient. However, when a plurality of dyes are used as a mixture, the dyeing behavior on the fiber differs depending on the type of the dye, so that it has been difficult to stably form a satisfactory black color under a certain condition.

In general, since disperse dyes are hardly soluble dyes, they are dispersed together with a dispersant to form fine particles when an ink is prepared. However, these dispersed particles gradually increase in particle size due to elapsed time due to storage, environmental changes in temperature and humidity, and dyes and dispersants are present at a high solid content. This causes clogging of the nozzles and discharge nozzles at the inlet of the ink chamber inside. As a result, blurring occurs in continuous ejection of ink, or ejection becomes impossible. Also, it may be difficult to re-emit light after a while after printing is stopped.

[0008]

SUMMARY OF THE INVENTION An object of the present invention is to provide a disperse dye ink and an ink-jet printing method which have high fastness and excellent black color development.
